METAL SHEET-PILING.

Patented April 24, 1906.

Application filed October 31, 1905. Serial No. 285,243.

To all w/umt it may concern:

Be it known that 1, JOHN R. WILLIAMs, a citizen of the United States, and a resident of East Orange, in the county of Essex and State of New Jersey, have inventel certain new and useful Improvements in Metal Sheet-Piling, of which the following is a speci- 'tication.

The invention relates to improvements in metal sheet-piling; and it consists in the novel features hereinafter described and claimed.

The invention pertains more particularly, though not exclusively, to improvements upon the metal sheet-piling shown and describel in Letters Patent No. 797,786, granted August 22, 1905, to J ohnR. I/Villiams and the objects of the present invention are, first, to increase the strength, efficiency, and desirability of the sections of piling shown and described in the said Letters Patent and,secon"ly, to provi e a metal sheet-piling comprised of sections in varying and reasonably short or con venient lengths and which when driven one upon the other in vertical series will present overlapping joints adapted to resist the passage of water or the like through the same.

More or less inconvenience is experience I in handling and (riving long lengths of metal sheet-piling, and with my invention such inconvenience is avoided, since in erecting a piling of any special height I provide sections in, say, fifteen and twenty-live foot lengths and alternate these in the Criving operation, whereby the sections may be conveniently handled and driven and which sections when constructed with the overlapping features hereinafter (escribel will when driven constitute a wall of metal sheet-piling adaptel to resist the passage of water through the same.

The metal sheet-piling described in my aforesai l Letters Patent is comprised of sections which overlap one another at their vertical e ge portions; but in the present instance I so construct the sections that the locking members of the several vertical sections forming a vertical length of piling will at their adjoining en's meet at points removed from the main e ges of the sections, whereby overlapping joints are formed with respect to sai l locking members. By making the sections of unequal lengths and alternating them in vertical series I produce a piling whose sections form a double wall, as described in my aforesai patent, but whose joints are overlapped, whereby the tendency to leakage through sai-l joints is obviatel without increasing the thickness or weight of the )iling.

The first feature of my invention is not confined to the use of sections of varying lengths nor to the overlapping of the locking members upon the sections adjacent thereto, but has to do specifically with the form and construction of the sections themselves, an 1 consists in the addition to the sections be scribed in my aforesaid Letters Patent of an additional flange at one edge of each section, whereby the strength and efliciency of the sections are increased and a mo lification in the formation of the locking members is permittel.

The invention will be fully un' crstood from the detailel J'escription hereinafter presenteil, reference being hail to the accompanying drawings, in which- Figure 1 is a top e "ge view of a metal sheetpiling comprising sections embodying my invention. Fig. 2 is a face view, partly broken away, of same. Fig. 3 is a detacheil top edge view of one section of the piling. Fig. 4 is a face view, partly broken away, of same. Fig. 5 is a sectional view, partly broken away, of the piling representel in Figs. 1 and 2, the

section being on the dottetl line 5 5 of Figs. 1

and 2; anl Figs. 6, 7, 8, 9, and 10 are corresponding views illustrating a slightly-mt'idifieil construction of piling embodying my invention, Fig. 6 being a top e 'ge view of same, Fig. 7 a face view, partly broken away, of same, Fig. 8 a top e ge view of one section of same, Fig. 9 a face view, partly broken away, of sail section, an 1 Fig. 10 a vertical section on the dotted line 10 10 of Figs. 6 and 7.

In respect to the first portion of my invention it may be said that the metal sheet-piling is formed of corresponding sections of the form and construction illustrated in Fig. 3, in which it will be seen that the section is formed from sheet metal rolled into the novel form presented and comprising a transverse diagonally-disposed member 11, parallel longitudinally-disposetl members 12 13, extending in opposite directions from the respective edges of said member 11, a flange or lockingtongue 14 along the outer edge of the member 12, a corresponding flange or lockingtongue 15 along the outer edge of the member 13, and a locking member 16, riveted to the face of the diagonal member 11 and offset at its end portions to form receiving spaces or recesses 17 18, respectively. Each section of the piling shown in Figs. 1 to 5, inclusive, is an exact duplicate of the section separately shown in Fig. 3, and when the section thus illustrated in Fig. 3 is compared with the individual section shown in Fig. 3 of my aforesaid Letters'Patent it will be seen that the first part of my invention resides in the addition to the sections shown in said patent of the flange or tongue 15 along the outer edge of the member 13 and in a modification in the formation of the locking member 16, whereby one edge of the latter is adapted to receive the flange 15 of an adjoining section to be applied to it. A further, though not necessary, change in the locking member 16 is that the upper or outer edge of said member, looking at Fig. 3, is not extended around the edge of the member 13, as is the case with the form of locking member shown in my aforesaid patent, and the purpose of this change in said edge of the looking member 16 is to enable the sections of piling when assembled in the manner shown in Fig. 1 to present parallel uniform surfaces at the extreme outer and inner sides of the same in lieu of the locking members presenting projecting edges, as shown in my aforesaid Letters Patent and also in Fig. 6 of the drawings of the present application, this feature of the piling presenting parallel uniform side surfaces being of importance in some classes of work.

In the assembling of the sections by driving them, as usual, the alternate sections will be oppositely disposed, as shown in Fig. 1 that is to say, the members 12 13 of one section will face in a direction oppositely to the direction in which the like members of the next adjoining sections will face, as illustrated.

Omitting the overlapping features and varying lengths of sections comprising the second part of my invention and considering for convenience of explanation that the sections are all of uniform length, the method of utilizing the invention or assembling the sections'may be described as follows: The sections are driven one after another, as usual, and after one section-say the left-hand one (shown partly broken away in Fig. 1)has been driven the next section will be appied thereto and driven, the said next or second section having its member 13 applied against the inner face of the member 12 of the first section, with the tongue or flange 15 of said member 13 within the receiving-recess 17 of the first section and the tongue or flange 14 of the first section within the receiving-recess 18 of the second section. The second section having thus been interlocked at two points upon the first section, said section will bedriven downwardly to position. lVhen the second section has reached its position, it will by means of the tongues or flanges 14 15, respectively, and the locking members 16, re-

spectively, of the first and second sections become locked to said first section, and the extended joint formed by the face-to-face contact of the member 12 of the first section with the member 13 of the second section -will resist the passage of water through the same, this resistance to the passage of the water being augmented by the confinement of the flange or tongue 15 of the second section by the locking member 16. of the first section and the inclosure of the flange or tongue 14 of the first section by the locking member 16 of the second section. After the second section has been driven the third section will then be applied to the second section and driven to position, the third section in its application to the second section having the outer face of its member 13 placed against the inner face of the member 12 of the second section, with the tongue or flange 15 of said member 13 in the receiving-recess 17 of the second section and the tongue or flange 14 of the second section in the receiving-recess 18 of the third section, and the third section when driven home will become effectually locked to the second section. The remaining sections will be applied one after another in series and driven to position, the relation of the first three sections being simply repeated throughout the extent of the piling. The sections are locked to one another in series and cannot be separated from one another in a lateral direction by reason of the presence H V of the angular tongues or flanges 14 15 and their engagement by the respective locking members 16. 15, provided along the outer edge of the member 13 of each section, materially strengthens said member and increases the efficiency of the same. The tongue or flange 15 facilitates the driving of the section and enables the member 13 to offer greater resistance to such obstructions as may be encountered during the driving operations. The tongue or flange 15 along the member 13 of each section also aids in looking the sections together, so that they may resist lateral strains, and this is of greater importance when the outer edge of the locking member 16 is, as shown in Figs. 1 and 3, not extended around upon the member 13, but terminates at the edge of the diagonal member 11 as distinguished from being carried upon the member 13, as shown in Fig. 8. It is desirable to increase the strength and efliciency of the member 13 by The angular tongue or flange the presence of the tongue or flange 15, and it tion to the member 13 of the angular flange or tongue 15 and in the adaptation of the locking member 16 to receive at its opposite edges the tongue 11 of one section and the tongue 15 of an adjoining section.

It will be unnecessary to describe in detail the special formation of the individual sections (illustrated in Figs. 6 to 10, inclusive,) since each of said sections is a duplicate of the section shown in 3, with the exception that the outer edge of the locking member 16'is carried upon the face of the member 13, Fig. 8, in the manner disclosed in my aforesaid Letters Patent instead of being cuto'tf at the edge of the diagonal member 11, as shown in Fig. 3. The locking member 16 will be of the form shown in Fig. 3 when it is desired that the outer side surtace of the piling shall be substantially uniform along a straight line, as shown in Fig. 1, and the locking member 16 will be of the construction shown .in Fig. 8 when it is not desired that the outer surface of the piling shall present such uniform surface along a straight line. The member .11) of the section shown in Fig. 8 has the tongue or flange 15, the same as shown in Fig. 3, and the sections illustrated in Figs. 6 to 10, inclusive, will be assembled or driven together in the manner hereinbefore described with respect to Figs. 1 to 5, inclusive. The first part of my invention will therefore be fully understood from the description hereinbefore presented.

The second part of my invention pertains to the making of the sections in varying lengths, in alternating them in vertical series. and in providing for the overlapping of the locking member on one section upon its next adjacent section in vertical series.

In the aforesaid Letters Patent the sections are shown as all of one length and the locking member as being coextensive in length with the section to which it is secured. In accordance with this part of my present invention the sections are of different lengths, one set of them being, say. fifteen feet long and the other set, say, twenty-five feet long, and the locking members 16, while preferably of the same length as the sections to which they are secured, are so disposed thereon that they project above their respective sections and do not extend to the lower edges of same, as more clearly illustrated in Fig. 1. In the drawings the shorter or fifteen-foot sections are numbered 20 and the longer or twentyl'ive-foot sections are designated by the numeral 21 and, referring to Figs. 1 to 5,inclu sive, it will be seen that the locking members 16 on the sections 20 21 extend a suitable distance above the upper edges of these sections and do not extend down to the lower edges of the sections, whereby the upwardly-extending portion of each locking member is enabled to overlap upon the diagonal member 1 lof the section directly above it. Inassemn: ill

bling the sections 21) 21 they are driven exactly in the manner hercinbefore described; but, taken in vertical series and remembering that the completed piling is of two thicknesses, I arrange to drive, say. the fifteen-foot lengths 20 to start one thickness of the piling and then twcnty-live-foot lengths 21 to start the other thickness of the piling. Figs. 2 and 5, and I then drive twenty-live-foot lengths 21 down to engage the upper edges of the aforesaid lengths 2t) and iiftcen-foot lengths 20 down to engage the upper edges of the first-driven longer lengths 21 .whereby, as shown in Fig. 5, the joint 22 between the sections 20 21 of the front thickness of the piling is fully covered by the lower long sections 21 of the rear thickness of the piling and the joint 23 between the sections 20 21 of the rear thickness of the piling is completely covered by the upper long sections 21 of the front thickness of the piling. By thus alternating the lengths 20 21 in vertical series in each wall or thickness of the piling and also alternating said lengths with respect to the two walls or thicknesses of the piling, so that a short length in one thickness is against a long length in the other thickness, the horizontal joints in one thickness of the piling are well covered over by solid portions of the other thickness of said piling, and leakage be tween these joints is prevented, which is at times a very desirable condition. if all the sections 20 21 were of the same length, it is obvious that the horizontal joints between them would extend through the entire thickness of piling and that leakage at these joints would result. in assembling the long and short lengths 2t) 21 in the manner described it is necessary that the locking members 16 extend above the upper edges of the sections carrying them and fail to extend to the lower edges of said sections; otherwise the ends of the locking members would come together and prevent the alternate arrangement of the sections 20 21 above described. The fact that the locking member on one section laps over upon the next adjacent section in vertical line with it also aids in preventing the leakage of water or mud through the wall of piling.

In lieu of constructing the locking members 16 each in one integral piece and securing the same on the sections so that they may extend above the upper edge thereof and not to the lower edge thereof, as shown in Fig. 4, said locking members may be formed in two parts, respectively numbered 31 in Fig. S), the part 31) being permanently riveted to the member 11 and not extending to either the upper or lower edge thereof, while the part 31 a shorter piece and may be riveted in position after the piling-section to receive it has been driven downward partly to its position in the earth. The advantage of making the locking member 16 in two parts 30 31 is that during at least a portion of the driving operation the upper edge of the piling-section may be left entirely clear to receive the blows from the instrument by which the driving is effected. In Fig. 7 the piling is shown as provided with the two-part locking members 16, which perform the same functions as the one-part looking members. (Shown in Figs. 2 and 4.)

The piling presented in Figs. 6 to 10, inclusive, is formed of the long and short sections 20 21, hereinbefore described with respect to Figs. 2 and 5, and therefore need not be specifically explained. Figs. 6 to 10, inclusive, are presented to exhibit the two-part locking members and the detail of carrying one edge of the locking member around upon the member 13, Fig. 8, this latter feature having been hereinbefore specifically referred to. Fig. 7 also illustrates what may be considered the opposite side of the piling to that shown in Fig. 2, the longer sections 21 being at the bottom in the front side of Fig. 7 and the shorter sections 20 being at the bottom in the front side of Fig. 2. By having all the short sections 20 of the same length and all the long sections 21 of the same length but two lengths of sections need be employed to secure the alternating disposition of the sections in the two thicknesses of the piling.
